The blatant herding over the past few days from pollsters is the only thing that makes me slightly worried about Clinton's chances.

Does this happen every election? It seems so weird. Just for 1-2 weeks ago the diff between to "A" pollster could be 4-8% points, which should be like this due to fluctuation. Now they all (except IBD/TIPP, but they will probably update and herd today) shows Clinton +3-5
